When air in the cylinder of a diesel engine is compressed it?
it gets hot, and ignites the diesel fuel that is injected by the fuel injectors.
What type of internal combustion engine has no spark plugs?
The diesel engine, which ignites the fuel vapors by compression within a preheated cylinder.
Why not diesel engine is spark ignited?
A gasoline injects fuel into the cylinder as it is filled with air, compresses it, then ignites the spark plug to trigger the power stroke. In a diesel engine air is compressed up to 3 times more causing a much higher cylinder temp. Once the air in the cylinder is hot diesel fuel is injected directly into the cylinder and is ignited by the high temperature.
What burns the fuel in cars?
The sparks plugs fire and ignite the fuel in a Gasoline engine, and compression compresses the fuel until it ignites in a Diesel engine.
What is different between gas and diesel engine?
diesal fuel ignites from pressure of the cylinder.gasoline ignites from the ignition spark from the distributor or coil pack.
Why is petrol not used in diesel engines or diesel in petrol engines?
Because the engines will not run with the wrong fuel to to their design. Although both diesel and petrol engines are internal combustion engines, they have differences that enable them to use these different fuels. A petrol engine ignites the fuel/air mixture by using a spark plug. A diesel engine in contrast has no spark but compresses air during the compression cycle. When air is compressed it heats up. Diesel is then injected into the cylinder and it ignites.
How is a gasoline engine different from a diesel engine?
A gas engine ignites gasoline in the piston chamber with a spark from a spark plug. The expanding gas then pushes the piston out and the motor moves forward. A diesel engine uses diesel fuel, different from gasoline, and the fuel is compressed by the piston until it ignites, sending the piston out. There are no spark plugs in a a diesel engine. Some diesel engines will have "glow plugs" which are used to initially start the engine but once started, compressing the fuel is the method of ignition.
Why does diesel engine don't need an outside source of ignition?
The fuel ignites under high compression.
Why compression ratio of petrol enine is 8 where as diesel engine is 22?
because a diesel engine ignites its fuel with pressure, and not with a spark like a petrol engine. that is why a petrol engine does not need as high a compression ratio as a diesel engine
Why in petrol engine spark plug is used but not in diesel engine?
Diesel engines run much higher compression than petrol engines. The higher compression makes the air in the cylinder so hot that the fuel self ignites. A petrol engine doesn't get warm enough for self ignition, so you have to add a spark from the spark plug to ignite the fuel.
What are gasoline engines and diesel engines?
The Diesel cycle engine was named after the German engineer who invented it, Rudolf Diesel. A Diesel engine uses two principles: air gets hot when you compress it, and fuel will ignite if it gets hot enough. The engine compresses air introduced into the cylinder to a very high pressure. When fuel is injected it immediately ignites.
Can you put gas in a diesel?
NO! Don't do it because, if you try to start it with regular unleaded gas in the diesel fuel tank, you're very likely to damage your engine!Gas ignites from sparks from spark plugs. Diesel is an oil and ignites from the high pressure produced by the piston in the cylinder. Therefore a diesel engine needs no spark plugs to produce the fire.For more information please see the answers to the Related Questions shown below.
